The rule of six
"In a classic experiment, psychology professor Stanley Milgram sent letters to acquaintances with the name of another person elsewhere in the world that they did not know, and with the simple instructions to pass the letter on to someone who ‘might know’ the target person. His remarkable findings was that, in most cases, the letter found its target within about six ‘hops’ between people.
This experiment has been repeated more recently using the internet and email, and has come up with the same conclusions: we are only about six steps away from anyone else in the world."
This is very interesting .Why six ? I can’t fathom the significance of the number .If this were true the diffusion that takes place in the political context or in the bizarre ideas or plain simple fashions can be predicted and quantified and may be ,controlled as the hops are just six covering a relatively smaller geographic area (unless it is on the internet).
